In order to cause the-shaft 83 and-the 'bit or auger. 87 carriedn thereon. to'workup or down while rotating --a pair :of jaws 88, 88

are pivotallysecured to the under side of the vertical bearing 72 :upon-a bol=t: 89, The innerr sides of-s'aid jaws'are out out, and provided with recesses '90,: 9(1), and within the recessed: portions of said jaws. is disposed, a j

nut comprising two correspondinglyishaped membersfil, 91.. which are provided upon their-outer sideswi-thf-ribs. 92,.adapted :to enter :the rec'esses90, 90. In order to main;

tain said nut-member 91, 91*. duly within. their'jaw members the same are secured by screws 93, -93 which 1 extend :through, the

sides of'saidjaws and .into the-nut mem-.

free ends with laterally projecting lugs 94,

disposed therein. "To facilitate the raising of'the shaft 83.and bit ona-uger 87 larger than the lug 94 to which latter are pivotallysecured the ends of links 95, 95 -within the outer ends of which is secured a I locking lever 96. The lever 96 is {provided at its inner end with a cam projection 97 which is adapted to engage with the outer surface of the lug 94 to hold thc'jaws 88, 88? locked together and maintain the nut therein in operative connection with the screwshaft 83.

The operation of the apparatus is as followsi The boom; members 53 when not in are carried upon pillow blocks 21", 21 arrai-iged upon the sides'iof-the'truck, and thetripod members 63 63", when dismounted,. ma'y also be carried upon the truck. The :faugershaft83 may alsobe carried upon the itruck and thebrack et 73 is normally thrown back' against the rear end of the truck frame 10 and secured by one ofthe chains 74. ;When it is desired to set the apparatus in operation .the lower ends of the boom mem .bers 53, 53"are first secured within the bearings 51, 51 provided at the rear end of the vwith the pulley '55 in position therebetween. The hoisting cable 86 is thenpassed over the pulley 55 and the end thereof secured-to one of the boom members 53. Hereupon the -boom members 53, 5.3 are raised to the position indicated at Fig. 1 by means of the hoisting mechanism arranged directly behind the cabin-14." In order to operate the hoisting mechanism the lever 82 is first ad justed to the horizontal position, as indicated in Fig. 1, in order to render the trans mission lever 16inoperative; and at the same 100 time operatively connect the shaft 50, which actuates the hoisting mechanism, with the transmission mechanism 13. Hereupon the transmission lever 1-5 is drawn rearwardly, as indicated in Fig. 1, whereupon the hoistmg drum 45 will be caused to rotate through the medium of the gear 78', shaft 75, gears 24, 26 and 46, and wind up the cable 86. As soon as the boom 'mem-bers 53, 53 have been raised to the position indicated in Fig. 11a 1 the foot piece 60 at the end of the guy 59 is secured to the forward transverse beam 20, and the guy'adjusted in position by the turn buckle 59. Hereupon the outer end of the cable 86 is disconnected from the boom and secured to the swivel 86 at the upper end of the threaded auger shaft 83, and said shaft 83 then raised to its uppermost position by E-the cable 86 and winding drum 85 by the mechanism heretoforedescrihed. Hereupon the bracket 73 is adjusted to its extended position, as shown at Figs. 1 and 2, and secured to such position by the chains 74, 74. The shaft 83 with its sleeve 80, and {whey '81 are then clamped within the split bearing 79. In order to operatively connect the said shaft 83 with the nut members 91 91, the lugs 94, 94 are released of their engagement with the cam '97 on the lever 96 and tho jaws are thereupon thrown apart. After the 139 screw has been adjusted to the described height the jaws 88, 88 are again brought together and secured to such position by the lever 96, and the cam 97 thereon brought into engagement with the lug 94.

In order to rotate the shaft 83 the pulley 47 upon the winding drum shaft 48 is placed in rotation by means of the large gear wheel 50 which has been operatively connected with the gear 24 of the shaft 75 through the slid able gear 26 arranged upon the shaft 25. The adjusting of said gear 24 is attained by means of the lever 42 arranged upon the outer side of the cabin 14. By raising the lever 42 to its uppermost position and causing the detent 43 to engage with the recess 42 in the segment 42 the link will cause the lower end of the bell-crank lever 34 to be depressed and itsshortcr end drawn toward the right (see Fig. 4), and in so doing move the shaft 29 through the medium of the link and collar 36 thereon. WVhen the shaft 29 is thus moved to the right (Fig. 4) the gear 20 will be caused to engage with the gears 24 and 50, and rotation will thereupon be communicated from the worm shaft to the worm 78 worm gear 7 8 and shaft 75. As the gear 26 is moved into engagement with the gears 24 and 50 the corresponding gear 26* at the opposite end of the shaft 25 will be moved out of engagement with its gear 24? on the shaft 75, and thegear 46 on the winding drum shaft 44. It will be understood, of course, that the pulley wheel 47 and the gears 50, 26 and 24, and shaft and connected parts are adapted to impart rotation to the auger shaft 83 only, and that mihen it is desired to raise said shaft 83 with and auger 87 out of the hole.

its auger 7, the gear 26 is shifted out of its engagement with the gears 24 and 50, and the gear 26* shifted into engagement with the gears 24* and 46, and the winding drum set in operation, whereupon the cable 86 in being thus wound up will raise the shaft 83 In order to permit of the shaft 83 being thus raised it will, of course, be necessary to release the lever 96 and then open the jaws 88, 88. When the borer shaft 83 is thus raised any matter which has been removed or cut away by the auger 87 will be supported upon the spiral disk portion thereof as shown at'Fig. 15, and in that way may be removed bodily from the opening or hole produced by the auger and i then moved aside while suspended from the the manner heretofore described, whereupon the cable 86 will be wound up thereon, and

parts while primarily designed as a means for supporting the auger shaft and auger, and for raising the same bodily in order to remove from the produced hole the material cut or loosened by said auger, and then again lowering said shaft and auger into the hole in order to continue the boring operation, may nevertheless be utilized without change or modification as a derrick or hoisting apparatus for raising and setting a pole in position within the hole, and for supporting the pole while the earth and material is being filled in around the same.
